Scripture: Genesis 4:13-15
Cain said to the Lord, “My punishment is more than I can bear.14 Today you are driving me from the land, and I will be hidden from your presence; I will be a restless wanderer on the earth, and whoever finds me will kill me.”
15 But the Lord said to him, “Not so; anyone who kills Cain will suffer vengeance seven times over.” Then the Lord put a mark on Cain so that no one who found him would kill him.
God punishes Cain for what he's done, but he also disallows anyone else from taking revenge on Cain. The mark of Cain is a call for others to forgive Cain rather than perpetuate the cycle of sin he created. God always interrupts sin with grace and forgiveness.
What cycle of sin is God wanting to interrupt in your life? Who has hurt you? Who do you need to forgive? Imagine them having the mark of Cain not as a sign of their sin but as God's call for you to forgive them.
